+SDEverywhere allows for unit testing, continuous integration, the ability to compare model runs, and a toolchain to transform a model into C, JavaScript, and WebAssembly code.
 
-Using SDEverywhere, you can deploy interactive System Dynamics models in mobile, desktop, and web apps for policymakers and the public.

 Here are some prominent current limitations:
 
 - Sketch information, the visual representation of the model, is not converted.
-- Only the most common [Vensim functions](https://www.vensim.com/documentation/index.html?20770.htm) are implemented.
